'cross-env' 未被识别为内部或外部命令，

Question

伙计们，你能帮我解决这个问题吗？我的 Laravel Mix 运行 npm 运行 dev 遇到了麻烦。我点击了下面的链接，但仍然存在错误。我的 OS 有问题吗？我试图删除 node_modules、运行 npm install --global cross-env。运行 NPM 再次安装。

https://github.com/JeffreyWay/laravel-mix/issues/478

这是我的版本：

Laravel混合版本：^2.0
节点版本（node -v）：8.9.0
NPM 版本 (npm -v)：5.6.0
OS: Windows7
XAMPP

> @ development C:\xampp\htdocs\codetinerant
> cross-env NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js

'cross-env' is not recognized as an internal or external command,
operable program or batch file.

您是否尝试按照链接的 dwoodward on the Github issue 的建议指定 cross-env 的路径。这进入你的 package.json 文件：

"dev": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"watch-poll": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack/bin/webpack.js --watch --watch-poll --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js",
"hot": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=development node_modules/webpack-dev-server/bin/webpack-dev-server.js --inline --hot --config=node_modules/laravel-mix/setup/webpack.config.js",
"production": "node node_modules/cross-env/dist/bin/cross-env.js NODE_ENV=production node_modules/webpack/bin/webpack.js --progress --hide-modules --config=node_modules/laravel-mix/setup/webpack.config.js"

这在 Laravel 的较新版本中可能已更改，但要点是您应该将 cross-env 更改为 node_modules/cross-env/dist/bin/cross-env.js。

首先，运行:

rm -rf node_modules
rm package-lock.json yarn.lock
npm cache clear --force

然后运行命令

npm install cross-env

npm install

然后你也可以运行

npm run dev

Answer 3

尝试将 npm bin 目录添加到您的系统路径例如 C:\Users\DELL\AppData\Local\Yarn\bin

Answer 4

我通过卸载节点然后运行以下命令解决了这个问题。

npm install -d
